Connector terminal having a two-part waterproof case

Abstract

A connector terminal includes a barrel part capable of attaching thereto a conductor exposed from an outer skin of an electric wire to cause to conduct and connect, and a terminal part caused to conduct to a mating terminal. The barrel part and an end of the electric wire are covered with a waterproof case made of resin to be made waterproof. The waterproof case is made of divided two case members, and is formed of the same material as the outer skin of the electric wire.

What is claimed is: 
     
       1. A connector terminal comprising a barrel part capable of attaching thereto a conductor exposed from an outer skin of an electric wire, and a terminal part adapted to connect to a mating terminal, the barrel part and an end of the electric wire being covered with a waterproof case made of resin to be made waterproof,
 wherein the waterproof case is made of two divided case members, and formed of the same material as the outer skin of the electric wire, 
 wherein the barrel part has a joining plate at the end of the electric wire which separates the barrel part from the terminal part and the joining plate extends outside the waterproof case, and 
 wherein a primer is previously applied only to the joining plate so that the primer is exposed to outside of the waterproof case. 
 
     
     
       2. A connector terminal as claimed in  claim 1 ,
 wherein the waterproof case is attached by ultrasonic bonding with the two case members mutually butted so as to cover the barrel part and the end of the electric wire. 
 
     
     
       3. A connector terminal as claimed in  claim 1 ,
 wherein the two case members each have a terminal close contact recess which is in close contact with an outer surface of the barrel part. 
 
     
     
       4. A connector terminal as claimed in  claim 1 ,
 wherein the two case members each have a terminal close contact recess which is in close contact with an outer surface of the barrel part, and 
 the terminal close contact recesses are located close to a location of the primer. 
 
     
     
       5. A connector terminal as claimed in  claim 1 , wherein the two case members attach to the joining plate at a first end and attach to the outer skin at the second end to form a waterproof seal.
